edible pen : dave hakkens
Even a calligrapher will admit to the occasional pen nibble. Dave Hakkens' concept project, the edible pen, gets real with this issue. It's constructed of candy parts, all of which can be consumed except for the very point of the pen. His design is thought out and careful; the candy won't melt in your hands and it's designed to be functional and enticing. Read more about his process here.
